Question

I get “Application did not close the cursor or database object that was opened here” error so I decided to pass datahelper between intents rather than close/open database for every intent..

I tried to put in Extras but didn’t work…

thanks for your help

this.dhn = new DataHelper(this);

public void StartGame(View v) { 
Intent intent = new Intent(StartScreen.this, Game.class); 
intent.putExtra("dhn",this.dhn); 
startActivity(intent); 
}

I changed my DataHelper to Singleton, looks able to use from any other intents without new helper.. looks working for now. going to test more

    private static DataHelper singleton;

    public static DataHelper getDataHelper(Context context) {
            if (singleton == null) {
                    singleton = new DataHelper(context);
                    OpenHelper openHelper = new OpenHelper(singleton.context);
                    singleton.db = openHelper.getWritableDatabase();
            }
            if(!singleton.db.isOpen()){
                    OpenHelper openHelper = new OpenHelper(singleton.context);
                    singleton.db = openHelper.getWritableDatabase();
            }
            singleton.context = context;
            return singleton;
    }

    private DataHelper(Context context) {
        this.context = context;
}
